Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13056, here are decompositions:
- 7 + 13049 = 13056
- 13 + 13043 = 13056
- 19 + 13037 = 13056
- 23 + 13033 = 13056
- 47 + 13009 = 13056
- 53 + 13003 = 13056
- 73 + 12983 = 13056
- 83 + 12973 = 13056
Showing the first eight; more decompositions exist.
